Apparently,the described embodiments are only a part of the embodiments of thepresent application, rather than all embodiments. Based on theembodiments in the present application, all of other embodiments, madeby the person skilled in the art without any creative efforts, fall intothe scope of the present application.

Reference is made to FIG. 1, which is a schematic diagram showing thestructure of a camera motor according to an embodiment of the presentapplication. In this embodiment, the camera motor may be arranged in adevice having a camera function, such as a cellphone, a pad, asingle-lens reflex camera.

In this embodiment, the camera motor may include the followingcomponents:

a lens assembly 1, a coil set 2, a holder 3, a coil bobbin assembly 4and a base 5. The coil set 2 includes an optical image stabilizer coil 6and an autofocusing coil 7.

The lens assembly 1 is connected with the coil set 2, the coil set 2 isarranged in the holder 3, the holder 3 is arranged in the coil bobbinassembly 4, and the coil bobbin assembly 4 is arranged in the base 5.

It is to be noted that, the lens assembly 1 in this embodiment may be anassembly which has a square structure at an outer periphery and has acircular structure at an inner side, as shown in FIG. 1, to allow thecircular lens to collect lights via the circular structure of its innerside and further to form an image.

The lens assembly 1 may be configured as a groove structure, as shown inFIG. 1, to allow other components including the coil set 2 to be movedtowards a left side in FIG. 1, and further to be embedded into the lensassembly 1, to achieve the connection of the lens assembly 1 and thecoil set 2 to each other.

In practical application, the coil set 2 may be arranged in the holder3. For the coil set 2, the holder 3 may function to support the coils tomaintain a certain shape, and the holder 3 can be arranged in the coilbobbin assembly 4, and the coil set 2 is supported by the coil bobbinassembly 4 via the holder.

Correspondingly, the coil bobbin assembly 4 may be embedded into thebase 5, and the base 5, after enclosing the coil bobbin assembly 4, theholder 3, the coil set 2, is connected with the lens assembly 1, forexample, by snap-fit connection or nested connection.

As shown in FIG. 1, the coil set 2 may achieve the forward-and-backwardmoving of the lens assembly 1 simply by pushing the lens assembly 1 infront of the coil set 2, without requiring pushing the structures suchas the holder 3, and the coil bobbin assembly 4, and further withoutrequiring a large pushing force, therefore the number of the coils inthe coil set may be reduced, and thus the volume of the coil set may bereduced.

As can be seen from the above solution, in the camera motor according tothis embodiment of the present application, by changing the mountingsequence of the coil bobbin assembly and the coil set, that is to say,the lens assembly in the camera motor is connected with the coil set,the coil set is arranged in the holder, the holder is arranged in thecoil bobbin assembly, and the coil bobbin assembly is then arranged inthe base, the power which is required to be provided by the coil set inpushing is reduced, thus may reduce the volume of the coil, and furtherreduce the volume of the camera motor and the overall weight of thedevice provided with the camera motor, and improve an experience of auser during using, and achieve the object of this embodiment.

Reference is made to FIG. 2, which is a schematic diagram showing thestructure of a camera motor according to an embodiment of the presentapplication. In the coil set 2 according to this embodiment, the opticalimage stabilizer coil 6 is arranged close to the position of the lensassembly 1, and the autofocusing coil 7 is arranged close to theposition of the holder 3.

That is to say, in this embodiment, after the autofocusing coil 7 isarranged on the holder 3, the optical image stabilizer coil 6 is thenarranged in front of the autofocusing coil 7, and then the lens assembly1 is assembled, to achieve arranging the optical image stabilizer coil 6being close to the lens assembly 1.

the optical image stabilizer coil 6 for optical image stabilizationapplies a force by four groups of magnets in an X direction and a Ydirection as in FIG. 2, and the autofocusing coil 7 for autofocusapplies a force by one groups of magnets in a Z direction as in FIG. 2,therefore, arranging the optical image stabilizer coil 6 in front of theautofocusing coil 7 in this embodiment, the number of the optical imagestabilizer coils 6 can be reduced, and thus the number of the coils inthe coil set 2 may be reduced and further the volume of the camera motormay be reduced, further the overall volume of the device provided withthe camera motor can be reduced.

In specific implementation, in the coil set 2 in this embodiment may betwo optical image stabilizer coils and two metal components.Specifically, the optical image stabilizer coils and the metalcomponents are arranged in a form of a ring-shaped structure, and eachof the optical image stabilizer coils is arranged in a position oppositeto a position of one of the metal components, connecting lines betweenthe optical image stabilizer coils and the metal componentscorresponding to the optical image stabilizer coils are perpendicular toeach other and intersect at a central point of the ring-shapedstructure.

An acting force may be generated between each optical image stabilizercoil and a metal component corresponding to the optical image stabilizercoil, after the optical image stabilizer coil is energized.

Based on the structure of the above coil set 2, an acting force isgenerated between each optical image stabilizer coil and the metalcomponent arranged corresponding to the optical image stabilizer coilafter the optical image stabilizer coil is energized. Because of thesquare-shaped arrangement of the optical image stabilizer coils and themetal components in the ring-shaped structure of the camera motor, thetwo acting forces are the same in magnitude and are perpendicular toeach other, thus, during practical application, the camera motor in thisembodiment may maintain the stability of the camera motor duringoperation while effectively achieving the optical image stabilization.

Also, while the acting force is generated between each optical imagestabilizer coil and the metal component corresponding to the opticalimage stabilizer coil, the electromagnet waves generated duringinteracting between the two optical stabilizer coils are avoided, andfurther the instability of the camera motor caused by intersecting ofthe electromagnet waves is avoided.

That is to say, in this embodiment, the instability of the camera causedby intersecting between the electromagnet waves is avoided by adoptingthe solution in which two optical image stabilizer coils are provided inthe camera motor, the volume of the camera is reduced, the stability ofthe force applying for optical image stabilization in the camera motoris ensured.

The metal component may be a metal ball, such as a steel ball, to allowthe steel ball to be magnetized by the optical image stabilizer coil atthe position corresponding to the steel ball, thereby generatingcorresponding magnetic force, and ensuring the accuracy of the opticalimage stabilization while reducing the volume of the camera.

In addition, based on the implementation structure of the optical imagestabilizer coil and the metal component hereinbefore, two autofocusingcoils may be provided in the coil set 2. The autofocusing coils 4 arearranged respectively between two adjacent optical image stabilizercoils and between two adjacent metal components, a connecting line ofeach autofocusing coil and a corresponding magnet in the camera motor isperpendicular to a plane in which the ring-shaped structure is located,thus, an acting force is generated between each autofocusing coil andthe magnet corresponding to the autofocusing coil after the autofocusingcoil is energized, to pull the lens in the camera motor to moveforward-and-backward, to further achieve autofocusing.

In another implementation, based on the implementation structure of theoptical image stabilizer coil and the metal component hereinbefore, oneautofocusing coil may be provided in the coil set 2, and theautofocusing coil is arranged between two adjacent metal components, anda connecting line between the autofocusing coil and the magnet in thecamera motor is perpendicular to a plane in which the ring-shapedstructure is located, thus, an acting force is generated between theautofocusing coiland the magnet 5 after the autofocusing coil isenergized, to pull the lens in the camera motor to moveforward-and-backward, to further achieve autofocusing.

In practical application, for further reducing the volume of the cameramotor, an elastic component may be provided in the camera motor. Theelastic component may be an element which bears and transmits aperpendicular load or a horizontal load and buffers and restricts thestriking caused by a plane, and it functions to bear and transmit aperpendicular load or a horizontal load when an external force acts, tobuffer and restricts the striking caused by an uneven plane such as arough road. Reference is made to FIG. 3, a schematic diagram showing thestructure of a camera motor is provided in an embodiment of the presentapplication. In this embodiment, the camera motor may further includethe following structure:

an elastic component 8, the elastic component 8 has a first endconnected with the lens assembly 1, and a second end connected with thecoil set 2.

Before the camera motor is started, the elastic component 8 is in afirst elastic state.

That is to say, the elastic component 8 may bear and transmit the loadbetween the lens assembly 1 and the coil set 2, and buffer and restrictthe striking acting force between the lens assembly 1 and the coil set2.

Therefore, in this embodiment, the elastic component 8 is used toprovide an elastic acting force while stabilizing the optical imagestabilizer coil 6 in the coil set 2 and the lens assembly 1, to reduce aforward pushing force and a backward drawing force to be provided by theautofocusing coil 7. For example, when the autofocusing coil 7 isrequired to push the lens assembly 1 to move forward, the elasticcomponent 8 provides an acting force of rebounding, and when theautofocusing coil 7 is required to push the lens assembly 1 to movebackward, the elastic component 8 may provide an acting force oftensioning, further the power to be provided by the autofocusing coil 7for achieving the autofocus may be reduced, and further the number ofthe coils may be reduced, and the volume of the camera motor may bereduced further.

The first elastic condition may be a compression state, in this case,the elastic component 8 has a pushing acting force of rebounding, andthe first elastic state may also be a stretch state, in this case, theelastic component 8 has a pulling acting force of drawing backward.

In practical implementation, the elastic component 8 may be grouped intotwo categories of metal and non-mental according to the materialadopted, and in specific implementation of this embodiment, the elasticcomponent 8 may be embodied as a spring, and the spring has acompression state or the stretch state.

Specifically, reference is made to FIG. 4, which is a schematic diagramshowing another structure according to an embodiment of the presentapplication. The camera motor may further include the followingstructure:

an elastic state setting structure 9, configured to set an elastic stateof the elastic component 8 before the camera motor is started.

In practical application, the first elastic state of the elasticcomponent 8 may be a compression state or may also be a stretch state ofa spring. For example, in the case that the first elastic state of theelastic component 8 is a compression state, the camera motor in thisembodiment may utilize the elastic component 8 to provide the powerrequired to push the lens assembly 1 forward by the autofocusing coil 7,and further, the number of the autofocusing coils 7 may be reduced inthis embodiment; and in the case that the first elastic state of theelastic component 8 is a stretch state, the camera motor in thisembodiment may utilize the elastic component 8 to provide the powerrequired to draw the lens assembly 1 backward by the autofocusing coil7, and further, the number of the autofocusing coils 7 may be reduced inthis embodiment. Therefore, in specific implementation of thisembodiment, the number of the coils can be reduced, to reduce the volumeof the camera motor.

Reference is made to FIG. 5, which is a schematic diagram showing thestructure of an electronic device according to an embodiment of thepresent application. The electronic device includes a camera motor 10.

The camera motor 10 includes the following structures:

a lens assembly 1, a coil set 2, a holder 3, a coil bobbin assembly 4and a base 5. The coil set 2 includes an optical image stabilizer coil 6and an autofocusing coil 7.

The lens assembly 1 is connected with the coil set 2, the coil set 2 isarranged in the holder 3, the holder 3 is arranged in the coil bobbinassembly 4, and the coil bobbin assembly 4 is arranged in the base 5.

It is to be noted that, the lens assembly 1 in this embodiment may be anassembly which has a square structure at an outer periphery and has acircular structure at an inner side, as shown in FIG. 1, to allow thecircular lens to collect lights via the circular structure of its innerside and further to form an image.

The lens assembly 1 may be configured as a groove structure, as shown inFIG. 1, to allow other components including the coil set 2 to be movedtowards a left side in FIG. 1, and further to be embedded into the lensassembly 1, to achieve the connection of the lens assembly 1 and thecoil set 2 to each other.

In practical application, the coil set 2 may be arranged in the holder3. For the coil set 2, the holder 3 may function to support the coils tomaintain a certain shape, and the holder 3 can be arranged in the coilbobbin assembly 4, and the coil set 2 is supported by the coil bobbinassembly 4 via the holder.

Correspondingly, the coil bobbin assembly 4 may be embedded into thebase 5, and the base 5, after enclosing the coil bobbin assembly 4, theholder 3, the coil set 2, is connected with the lens assembly 1, forexample, by snap-fit connection or nested connection.

As shown in FIG. 1, the coil set 2 may achieve the forward-and-backwardmoving of the lens assembly 1 simply by pushing the lens assembly 1 infront of the coil set 2, without requiring pushing the structures suchas the holder 3, and the coil bobbin assembly 4, and further withoutrequiring a large pushing force, therefore the number of the coils inthe coil set may be reduced, and thus the volume of the coil set may bereduced.

As can be seen from the above solution, in the electronic deviceaccording to the this embodiment of the present application, by changingthe mounting sequence of the coil bobbin assembly and the coil set inits camera motor, that is to say, the lens assembly in the camera motoris connected with the coil set, the coil set is arranged in the holder,the holder is arranged in the coil bobbin assembly, and the coil bobbinassembly is then arranged in the base, the power which is required to beprovided by the coil set in pushing is reduced, thus may reduce thevolume of the coil, and further reduce the volume of the camera motorand the overall weight of the electronic device provided with the cameramotor, and improve an experience of a user during using, and achieve theobject of this embodiment.

In the electronic device according to this embodiment, in the coil set 2according to this embodiment, the optical image stabilizer coil 6 isarranged close to the position of the lens assembly 1, and theautofocusing coil 7 is arranged close to the position of the holder 3.As shown in FIG. 2.

That is to say, in this embodiment, after the autofocusing coil 7 isarranged on the holder 3, the optical image stabilizer coil 6 is thenarranged in front of the autofocusing coil 7, and then the lens assembly1 is assembled, to achieve arranging the optical image stabilizer coil 6being close to the lens assembly 1.

The optical image stabilizer coil 6 for optical image stabilizationapplies a force by four groups of magnets in an X direction and a Ydirection as in FIG. 2, and the autofocusing coil 7 for autofocusapplies a force by one groups of magnets in a Z direction as in FIG. 2.Therefore, arranging the optical image stabilizer coil 6 in front of theautofocusing coil 7 in this embodiment, the number of the optical imagestabilizer coils 6 can be reduced, and thus the number of the coils inthe coil set 2 may be reduced and further the volume of the camera motormay be reduced, further the overall volume of the electronic deviceprovided with the camera motor can be reduced.

In practical application, for further reducing the volume of the cameramotor and the electronic device, an elastic component may be provided inthe camera motor of the electronic device. The elastic component may bean element which bears and transmits a perpendicular load or ahorizontal load and buffers and restricts the striking caused by aplane, and it functions to bear and transmit a perpendicular load or ahorizontal load when an external force acts, to buffer and restricts thestriking caused by an uneven plane such as a rough road. As shown inFIG. 3, in the electronic device according to this embodiment, thecamera motor 10 may further include the following structure:

an elastic component 8, the elastic component 8 has a first endconnected with the lens assembly 1, and a second end connected with thecoil set 2.

Before the camera motor 10 is started, the elastic component 8 is in afirst elastic state.

That is to say, the elastic component 8 may bear and transmit the loadbetween the lens assembly 1 and the coil set 2, and buffer and restrictthe striking acting force between the lens assembly 1 and the coil set2.

Therefore, in the electronic device according to this embodiment, theelastic component 8 in the camera motor 10 is used to provide an elasticacting force while stabilizing the optical image stabilizer coil 6 inthe coil set 2 and the lens assembly 1, to reduce a forward pushingforce and a backward drawing force to be provided by the autofocusingcoil 7. For example, when the autofocusing coil 7 is required to pushthe lens assembly 1 to move forward, the elastic component 8 provides anacting force of rebounding, and when the autofocusing coil 7 is requiredto push the lens assembly 1 to move backward, the elastic component 8may provide an acting force of tensioning, further the power to beprovided by the autofocusing coil 7 for achieving the autofocus may bereduced, and further the number of the coils may be reduced, and thevolume of the camera motor may be reduced further.

The first elastic condition may be a compression state, in this case,the elastic component 8 has a pushing acting force of rebounding, andthe first elastic state may also be a stretch state, in this case, theelastic component 8 has a pulling acting force of drawing backward.

In practical implementation, the elastic component 8 may be grouped intotwo categories of metal and non-mental according to the materialadopted, and in specific implementation of this embodiment, the elasticcomponent 8 may be embodied as a spring, and the spring has acompression state or the stretch state.

Specifically, as shown in FIG. 4, in the electronic device according tothis embodiment, the camera motor may further include the followingstructure:

an elastic state setting structure 9, configured to set an elastic stateof the elastic component 8 before the camera motor 10 is started.

In practical application, the first elastic state of the elasticcomponent 8 may be a compression state or may also be a stretch state ofa spring. For example, in the case that the first elastic state of theelastic component 8 is a compression state, the camera motor in thisembodiment may utilize the elastic component 8 to provide the powerrequired to push the lens assembly 1 forward by the autofocusing coil 7,and further, the number of the autofocusing coils 7 may be reduced inthis embodiment; and in the case that the first elastic state of theelastic component 8 is a stretch state, the camera motor in thisembodiment may utilize the elastic component 8 to provide the powerrequired to draw the lens assembly 1 backward by the autofocusing coil7, and further, the number of the autofocusing coils 7 may be reduced inthis embodiment. Therefore, in specific implementation of the electronicdevice according to this embodiment, the number of the coils can bereduced, to reduce the volume of the camera motor and the electronicdevice, to further improve the experience of the user during using.

Besides, currently, in a camera motor of a mobile device such as acellphone, magnetic coils are generally used to provide a power forimage stabilization, and in a ring-shaped frame of a camera motor, foursymmetrically distributed image-stabilizing magnetic coils are provided.Two image-stabilizing magnetic coils at opposite positions will generateelectromagnetic waves in an X direction and a Y direction after beingenergized, to generate an acting force to push the lens connected withthe frame to move in the X direction and the Y direction, thusstabilizing the lens.

In the camera motor, the electromagnet waves intersect in the Xdirection and the Y direction, and the intersection of theelectromagnetic waves may cause instability of the motor in a certaindegree, and lens shaking occurs.

Reference is made to FIG. 6, which is a schematic diagram showing thestructure of a camera motor according to an embodiment of the presentapplication; specifically, the camera motor in this embodiment may bearranged in a device with a camera function, such as a cellphone, a pad,and a single-lens reflex camera.

In this embodiment, the camera motor may include the followingstructures:

at least two optical image stabilizer coils 6 and at least two metalcomponents 20.

Specifically, the optical image stabilizer coils 6 and the metalcomponents 20 are arranged in a form of a ring-shaped structure 30, andeach optical image stabilizer coil 6 is arranged in a position oppositeto a position one metal component 20, connecting lines between theoptical image stabilizer coils 6 and the metal components 20 oppositethereto are perpendicular to each other and intersect with each other ata central point q of the ring-shaped structure 30.

An acting force is generated between each of the optical imagestabilizer coils band a metal component 20 corresponding thereto whenoptical image stabilizer coils 6 are energized.

In this embodiment, the camera motor including therein two optical imagestabilizer coils 6 and two metal components 20 is taken as an example.In this embodiment, the two optical image stabilizer coils 6 and the twometal components 20 in the camera motor are arranged in the form thering-shaped structure 30, as shown in FIG. 6, the two optical imagestabilizer coils 6 are arranged adjacent to each other in thering-shaped structure 30, and the two metal components 20 are alsoarranged adjacent to each other in the ring-shaped structure 30. Eachoptical image stabilizer coil 6 is arranged opposite one metal component20, and connecting lines between the optical image stabilizer coils 6and the metal components 20 opposite thereto are perpendicular to eachother and intersect with each other at the central point q. As shown inFIG. 7, in the ring-shaped structure 30 of the camera motor, the twooptical image stabilizer coils 6 and the two metal components 20 arearranged uniformly so as to form a square.

Therefore, an acting force is generated between each of the opticalimage stabilizer coils 6 and the respective metal component 20 arrangedopposite thereto when optical image stabilizer coils 6 are energized.Because of the square arrangement structure of the optical imagestabilizer coils 6 and the metal components 20 in the ring-shapedstructure 30 of the camera motor, two such acting forces are the same inmagnitude, and opposite and perpendicular to each other, thereby, in thepractical application of the camera motor in this embodiment, an opticalimage stabilization can be achieved effectively, thus keepingstabilization in the operation of the camera motor.

Furthermore, while the acting force is generated between each of theoptical image stabilizer coils 6 and the metal component 20corresponding thereto, electromagnetic waves are prevented from beinggenerated between the two optical image stabilizer coils as interactingwith each other, and thus instability of the camera motor from beingcaused by the intersection of the electromagnetic waves is avoided, suchthat the object of this embodiment is achieved.

As can be seen from the above solution, in the camera motor according tothe embodiment of the present application, by providing the metalcomponents in positions opposite to those of the two optical imagestabilizer coils in the camera motor, an acting force is generatedbetween the optical image stabilizer coiland the metal componentcorresponding thereto when optical image stabilizer coil is energized,and optical image stabilization may be achieved, and also there will beno electromagnetic waves between the optical image stabilizer coil andthe metal component, such that there will be no intersectingelectromagnetic waves in the camera motor, thereby avoiding instabilityof the camera motor and lens shaking occurring caused by intersecting ofthe electromagnetic waves, thus achieving the object of this embodiment.

In addition, in practical application, a magnet 50 is provided in thecamera motor, to generate an acting force for autofocus between themetal coil and the magnet 50.

In this embodiment, the two autofocusing coils 7 provided in thecamera motor are respectively arranged in the positions shown in FIG. 7,accordingly, the magnets 50 in the camera motor are arranged inpositions corresponding to those of the two autofocusing coils 7, asshown in FIG. 8, connecting lines between the two autofocusing coils 7and the magnets 50 arranged corresponding to the autofocusing coils 7are perpendicular to the plane in which the ring-shaped structure 30 islocated. Thus, when each of the autofocusing coils 7 is energized, anacting force may be generated between each of the autofocusing coils 7and the magnet 50 arranged corresponding thereto, to pull the lens inthe camera motor to move forward and backward, to further achieveautofocusing.

Reference is made to FIG. 9, which is a schematic diagram showing thestructure of a camera motor according to an embodiment of the presentapplication; specifically, the camera motor in this embodiment mayfurther include the following structure:
